I currently run on an xp system. I'm not too bright with computers.
>From the internet' we are receiving e-mails, alerts and info on undesirable sites. I want to remove all of these & prevent it from re-occuring. On the internet, I keep getting a web-encounter highlighting access to specific porn sites. With a young daughter using the computer, this is a problem.
I would prefer to remove the whole of my data from this system including the original set up program for this machine then re-load it. all help would be very appreciated.
